B Redundant Gateway systems
B.1 Overview
Redundancy for the Emerson Wireless 1410S Gateway increases the availability of the
wireless field network by providing two sets of physical hardware which operate as a single
Gateway system. This section covers setup and installation of a redundant Gateway
system. It also covers diagnostics and integration to help monitor the health of the
redundant Gateway system.

• Illustration of maximum redundancy including dual switch and UPS
• Understanding how the fail over works and experience to expect
• How to leverage the multimaster capability for Modbus
B.2 Requirements
Wireless Gateway
• Firmware version 4.3.19 or greater is recommended
• RD option for Gateway redundancy
• Static IP address
• Must have matching output protocols (e.g. Modbus
Host system
• Ethernet connection for Modbus TCP or OPC DA communications
• Serial (RS-485) connection for Modbus RTU communications
B.3 Setup
When configuring redundant Gateways, it is only necessary to configure one system. The
other Gateway will be configured automatically when it is paired with the first Gateway.
Choose one Gateway as the starter Gateway. For the purposes of this document, it will be
referred to as Gateway A. The other Gateway will be referred to as Gateway B.
To configure redundancy system settings:
Procedure
1. Connect a PC/laptop to the Ethernet 1 port on Gateway A.
2. Log in using the admin user account.
3. Navigate to System Settings → Gateway → Redundancy.
4. Gateway A factory serial number will be assigned to Gateway A.
5. Gateway B factory serial number will be assigned to Gateway B.
